“Dream a Little Dream of Me” is a song, from 1931, with music by Fabian Andre and Wilbur Schwandt and lyrics by Gus Kahn.

It was first recorded in February 1931 by Ozzie Nelson and also by Wayne King and His Orchestra, with vocal by Ernie Birchill. A popular standard, more than 60 other versions have been recorded, but some of the highest chart ratings were in 1968 by Mama Cass Elliot with The Mamas & the Papas.

“Dream a Little Dream of Me” was recorded for the Mamas & the Papas April 1968 album release The Papas & The Mamas. The group had often sung the song for fun, having been familiarized with it by member Michelle Phillips, whose father had been friends with the song’s co-writer, Fabian Andre, in Mexico City where Michelle Phillips’ family had resided when she was a young girl.

“Mama” Cass Elliot suggested to group leader John Phillips that the group record “Dream a Little Dream of Me”. According to him she was unhappy while recording the song, objecting to its campiness. However, Elliot herself would later tell Melody Maker: “I tried to sing it like it was 1943 and somebody had just come in and said, ‘Here’s a new song.’ I tried to sing it as if it were the first time.” (source Wikipedia)
